HAIR-STEAMING DEVICE.

Specification of Letters Patent.

Application filed January 3, 1914. Serial No. 810,136.

, tan, city, county, and State of New York,

have invented certain new and useful Improvements in Hair-Steaming Devices, of which the following is a specification.

Our invention relates to hair steaming and waving devices and constitutes an improvementindevices of the character forming the subjectmatter of our Patent No.

, 1OQ93G1, June 11, 1912.

lVhen the hair has been waved following the process outlined in the above identified patent the waving usually lasts for a period of from six months to one year but during this time the new hair grows out about an inch and as this hair is naturally unwaved it destroys the effectiveness of the waved hair and it has heretofore been necessary to rerwave the entire head of hair at great expense of time and labor.

Accordingly one of the objects of the invention is to provide -a heating device of the above indicated character particularly designed to concentrate the heat to the wrapped portions of the hair adjacent the head thereby to wave the hair at this place without aife'cting the outer portions of the wave coil.

Another object of the invention is to provide a light, compact and balanced hair waving device of simplified construction, the parts of which may be readily assembled as units and effectively secured in place. Y

Various other objects and advantages will be obvious from an inspection of the illustration of one form ofdevice embodying our invention and in part will be more fully disclosedv in the following detailed description thereof.

In the accompanying drawings: Figure 1 is a side elevation of one form of our invention, shown in ,position on a personshead; Figs. 2 and 4 are enlargedlongitudinal sectional views taken axially through the vdevice shown in Fig. 1-, and at right angles to each other; Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2 and lookingjn the direction indi- 55,1 ofrelatively high heat conductivity made cated by the arrow; and Fig. 5 is a rear and is bound by an asbestos cord 16.

preferably of brass and when used for the particular purpose for which this device has been designated is of about one inch in length and has a smooth bore of uniform cross-sectional area. Extendingoutwardly from one end of the tube 1, herein desig- Patented July 14, 1914..

nated as the rear end, is a plate 2 to which is attached a suitable handle 3 preferably covered by suitable insulating material 4. Afiixed to the plate 2, and preferably integral therewith, is a projectinglug 5 carrying an insulating bushino 6 to guide the electric conductors 7 therethrough to the heating coil hereinafter described. This lug may also contain an aperture 8 by means of which the device may be suspended in counterweighted position over a suitable pulley as is common with the suspension of devices of this character.

Surround-ing the tube 1 and suitably fastened to the plate 2 is an insulating ring 9 preferably of a compressed asbestos. composition. The portion of the ring adjacent the bushing 6 has a recess 10 to accommodate the conductor 7, andthis ring carries a pair of oppositely disposed binding posts .11, each post having a plurality of nuts 12 threaded thereto. The conductors 7 lead respectively to the binding posts and are held in engagement therewith by the inner nut pressing the same against the adjacent face of the ring 9.

A sleeve 13 of insulating material, preferably mica, surrounds the tube 1 and electrically insulates the same from an electric heating coil 14, the ends of which lead respectively to the binding posts 11 and are held thereto between the nuts 12. The coil 14: is inclosed within aninsulating layer 15 Inclosing this heating device is an outer tubular member 17, preferably of metal, the rear end of which abuts'the front face of the ring 9 and the front/end of which is frusto-conical as shown at 18. The adjacent nently fastened together as by Hanging. or

- welding to form in effect a metallic heating ring 18. The heating coil 14: has its front end disposed within the angle formed by these tubular members and as close as'possible to the front end or nose of the device. The outer tubular member 17 ispreferably in closed within an insulating outer covering 19.

In operation it will be understood that the hair is coiled and treated as more fully dcscribed'in the above identified patent and drawn through the tubular member 1 until the pointed trout nose is brought fiat against or close to the head. The current is then permitted to traverse the heating coil H which tends to concentrate the'heat as close to the base of the coil of hair as possible as there is no insulating member between the heating device and the inner and outer tubular members and at the same time there is provided suflicient material to give a material heat capacity.

This device is of a minimum diameter so that a large number of the devices may be positioned at the same time on the head. The inner member is'opened at both ends so that the hair may be drawn therethrough and the part not being waved may be suita-bly protected from any heating action of the device and is approximately balanced about the rear plate so as to relieve as much strain as possible on the hair.

Having thus described our invention, we

- claim:

mit other portions to extend beyond opposite ends thereof, an outer tubular member hav-' mg a conical nose aflixed thereto at one end and a heating means disposed between said members and filling the space adjacent the connection between the inner and outer tubular members whereby a high degree of heat may be concentrated at one end of the device to heat the portion of the coiled hair adj acent the head.

2. A device of the class described comprising an open ended inner tube of substantially uniform bore, an outwardly extending rear plate affixed thereto whereby said device may be supported in substantially horizontal position, an insulating ring surrounding said tube and disposed adjacent said plate,'

an outer tube having a rear end telescoping said ring abutting said plate and having a relatively blunt frusto-conical front end engaging said inner tube, heating meansdisposed between said tubes and within the trusto-conical endand an electric conductor leading through said rear plate to said heating means.

A hair'waving device adapted to be placed on a persons head comprising a member including two telescoped metallic tubes fastened together at one end to form a closed space adapted to contain a coil of the persons hair, an electric heating coil carried by said member between the metal tubes and adjacent the closed end, an outwardly extending plate affixed to said member at the opposite end, a handle carried by said. plate, means carried by the plate for directing an electric conductor to said heatingcoil, said plate including a projecting lug having a holding aperture therein whereby said de-- vice may be supported in position adjacent a persons head.

t. -A device of the class described, comprising an open ended tubular member of: relatively high heat conductivity and adapted to surround a portion of a coil of hair adjacent the persons head. and permit; other portions to extend beyond opposite ends thereof, a heating means surrounding said tubular member, a sheet of insulating material disposed between the "heating means and said tubular member, and means for supporting said device in position.

5. In a device of the class described, a heating means adapted to surround av strand of hair adjacent the persons head, the end adapted to be disposed adjacent the head including a metallic heating ring, an inclosed heating device disposed on the side of the ring opposite the side adapted to be positioned adjacent the persons head, the portion of said heating device adj accnt the ring being of frusto-conical form with the smaller end disposed close to the ring to maintain the same in heated condition.

6. A device of relatively high heat capacity for treating the portion of a coil of a persons hair adj accnt the head without attecting the remaining portion of the coil, said device comprising an inner tubular member adapted to contain the said portion of: hair and to permit the other portion to extend therefrom, an outer tubular member being trusto-conical with the smaller end atfixed to the inner member to form a joint to' fit against or near to the persons head, the portion of said member forming the joint being of relatively high heat conductivity, a heating coil disposed between said tubular members close to the joint, said coil generating more heat adjacent the joint than at points fartherremoved from the joint wherebyrclative high temperatures can be ob-.

tained at one end of the device,,so that the hair can be 'wavcd as close to the head as possible. i

7. A device o the class described, comprising a rear wall in the form of a circular disk forming a support for the device at the rear end of the same and having an opening therethrough, a short metal tube open at both ends and having one end inserted through the opening in said wall and fastened to the wall, the inner portion of said rear wall being reduced to form an annular shoulder, an outer tube having one end inclosing said shoulder, abutting against said rear wall and spaced from said inner tube, an electric heating means disposed between said tubes and in advance of said rear wall,
